Abstract:
The invention relates to a surgical instrument (100; 200) comprising: an elongated arm (111; 207) according to a longitudinal axis and having a distal end (105; 204) mounted with a pivot joint on the elongated arm according to an axis substantially orthogonal to the longitudinal axis; a drive shaft (103; 3), substantially coaxial with the elongated arm, comprising means forming a universal joint (104; 206) facing the pivot joint; and, distal tool (9) securely fastened on the drive shaft and rotatively mounted on and in the extension of the distal end of the elongated arm, such that the distal tool has two rotational degrees of freedom, distinct and independent of each other, one being around an axis substantially perpendicular to the longitudinal axis of the elongated arm and the other being around an axis substantially collinear to an own axis of the distal tool, characterized in that the means forming a universal joint comprise a flexible drive sleeve (104; 206).
Abstract:
The invention relates to a system for controlling with respect to a body of a patient, displacement of an intervention device having an end intended to be inserted in the body of the patient through a point of penetration comprising a base, a first portion with an arc member, a second portion with a carrier member slidably mounted on the arc member and a third portion with a holding member and a sliding member.
Abstract:
The invention relates to a surgical instrument comprising: - a distal tool (5) securely fastened at a distal end of a rotation shaft (4) and rotatably mounted on and in the extension of a distal member (30) rotatably mounted at an end of an elongated arm (3), - motorized means (20) for actuating the distal motion of the distal tool (5) and further comprising controlling means (21) for a user to control the motorized means (20); characterized in that the controlling means (21) comprise electronic components (210) for actuation of the motorized means (20), and switch elements (211) for the user to control the electronic components (210), the switch elements (211) comprising at least one magnet (2110) for contactless signal transmission to hall sensors (2100) of the electronic components (210), wherein the switch elements (211) comprise an outer knob (2111) and an inner knob (2112), with the magnet (2110) being fastened to the outer knob (2111) and being mounted in translation within a longitudinal groove (2113) provided in the inner knob (2112) along an axis parallel to the longitudinal axis, said inner knob (2112) being rotatably mounted around the longitudinal axis.
